laravel 7 将对象数组插入数据库

Question

这是我的数据

answers: [
{text: "dsfdsfjds", correct: "false"}
{text: "asjdkjsa", correct: "true"}
{text: "sadasdsad", correct: "false"}
}

我试过的

$answers[] = $request->answers;
        $question = Question::create([
            'question' => $request->question,
            'date' => $request->date
        ]);
        if($question) {
            foreach($answers as $ans) {
                $anss = Answer::create([
                    'question_id' => $question->id,
                    'text' => $ans->correct,
                    'correct' => $ans->correct,
                ]);
            }
        }

我收到这个错误

Trying to get property 'correct' of non-object"

请指导我如何将数据插入数据库。

Answer 1

我猜你的问题出在这一行：

$answers[] = $request->answers;

删除括号并重试：

$answers = $request->answers;

Answer 2

根据您的描述，我假设 answers 是一个 json 对象数组。您应该解码 json 对象以访问其属性。在foreach循环的开头添加这个

$json_decoded_answer = json_decode($ans);

然后你可以这样做

$anss = Answer::create([
                'question_id' => $question->id,
                'text' => $json_decoded_answer->correct,
                'correct' => $json_decoded_answer->correct,
            ]);

Answer 3

Trying to get property 'correct' of non-object"

尝试这样做

$answers = $request->answers;
        $question = Question::create([
            'question' => $request->question,
            'date' => $request->date
        ]);
        if($question) {
            foreach($answers as $ans) {
                $anss = Answer::create([
                    'question_id' => $question->id,
                    'text' => $ans['text'],
                    'correct' => $ans['correct'],
                ]);
            }
        }

我只是将这个 $answer[] 更改为 $answer 并使用了一个数组而不是对象
